Surface Chemistry mcq question image

A. unbalanced bombardment of particles by molecules of the dispersion medium

B. attractive forces between dispersed phase and dispersion medium

C. larger size of the particles due to which they keep colliding and settling down

D. conversion currents formed in the sol.

Answer : unbalanced bombardment of particles by molecules of the dispersion medium

Solution :
The colloidal particles are in a continuous zig-zag motion due to unbalanced bombardment of the particles by molecules of the dispersion medium.
